登錄到網站與asihttprequest

Question

我一個試圖登錄到一個簡單的網頁我做了，我只好在代碼 - （IBAction爲）{}

當我按下它應該獲取數據按鈕

這裏是我的代碼

-(IBAction)fetchData:(id)sender { 
NSURL *url = [NSURL URLWithString:@"http://rssit.site90.com/login.php"]; 
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; 
[request setRequestMethod:@"POST"]; 
[request addPostValue:@"" forKey:@"username"]; 
[request addPostValue:@"" forKey:@"password"]; 


[request setDelegate:self]; 
[request startAsynchronous]; 
NSLog(@"%d, %@", request.responseStatusCode, [request responseString]); 

} 

當我運行它，它會返回0（零）我看着爲asihttprequest頭文件，這意味着沒有身份驗證需要的？但該網站上有登錄。

進出口投入的用戶名和密碼，我只是didnt列表它放在這裏

重寫代碼如下，賓果....

-(IBAction)fetchData:(id)sender 
{ 
    NSURL *url = [NSURL URLWithString:@"http://rssit.site90.com/login.php"]; 
    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; 
    [request setRequestMethod:@"POST"]; 
    [request addPostValue:@"" forKey:@"username"]; 
    [request addPostValue:@"" forKey:@"password"]; 
    [request setDelegate:self]; 
    [request startAsynchronous]; 

    //Add finish or failed selector 
    [request setDidFinishSelector:@selector(requestLoginFinished:)]; 
    [request setDidFailSelector:@selector(requestLoginFailed:)]; 

    NSLog(@"%d, %@", request.responseStatusCode, [request responseString]); 

} 

- (void)requestLoginFinished:(ASIHTTPRequest *)request 
{ 
//Check response of request here and act accordingly 
NSString *yourResponse = [request responseString]; //corrected here please change it to responseString 
//Parse above response and check it. 
} 


- (void)requestLoginFailed:(ASIHTTPRequest *)request 
{ 
//some error was there processing request 
//Check error 
NSError *error = [request error]; 
NSLog(@"Failed ---> %@",[error localizedDescription]); 
} 

當你做出要求，你需要等到請求完成儘管你正在提出異步請求，因爲它是登錄信息，你需要等到響應結束。
